Using the PhaseManager Tool
PhaseManager Overview
The PhaseManagerâ„¢ tool lets you add equipment phases to your controller. An
equipment phase helps you lay out your code in sections that are easier to write,
find, follow, and change.

Term Description
Equipment phase • As with a program, an equipment phase is run in a task and is given a set of routines and tags.
• Unlike a program, an equipment phase runs by a state model and lets you do one activity.
State model • A state model divides the operating cycle of your equipment into a series of states. Each state is an instant in the operation of the equipment, the
actions, or conditions of the equipment at a given time.
• The state model of an equipment phase resembles that of the S88 and PackML state models.
State machine An equipment phase includes an embedded state machine that does the following:
• Calls the routine associated with an active state
• Manages the transitions between states with minimal coding
• Makes sure that the equipment goes from state to state along an allowable path
PHASE tag When you add an equipment phase, RSLogix 5000 software makes a tag for the equipment phase. The tag uses the PHASE data type.
